Last night another cat was found dead and South Norwood Animal Rescue Liberty (SNARL) warned today that the Croydon Cat Killer may strike again.

Over the festive period five cats were kelled around Northampton and there were hopes police had finally brought the twisted killer’s four year spree to an end when they made an arrest.

SNARL said: ‘We were made aware of the arrest at the time. It’s one of those things that are part and parcel of a large, ongoing and complex investigation – people get looked into and spoken with on an ongoing basis.

‘The person or persons known as the UK animal killer remains active and we continue to attend incidents, the latest one yesterday.’

SNARL warned that reports of the arrest could have enraged the killer and he might go on another spree to prove he is still free.

In a statement it said: ‘The fear is the real killer will be infuriated by the reports and will want to prove he is still at large, and will taunt his pursuers by embarking on a new orgy of cat slayings to show he’s still one step ahead of his hunters.’

The cat killer started murdering felines in South London in 2014 and is believed to have killed and maimed around 400 animals around a 117-mile stretch of the M25 motorway.

Pet rabbits as well as wild deer, squirrels and foxes have been his targets too often killing and dismembering them using a machete or garden sheers.

A £10,000 reward is now being offered for information that leads to his capture.

Two groups, including People for the Ethical Treatment of Animals, are each offering a £5,000 reward.
